PRECAUTIONS DURING OPERATION
● Do not attempt to operate the unit with wet hands, this could cause fatal
accident.
● Do not direct the cool air coming out from the air-conditioner panel to face
household heating apparatus as this may affect the working of apparatus
such as the electric kettle, oven etc.
● Do not place plants directly under the air fl ow as it is bad for the plants.
● Please ensure that outdoor mounting frame is always stable, fi rm and
without defect. If not, the outdoor unit may collapse and cause danger.
● Do not splash or direct water to the body of the unit when cleaning it as
this may cause short circuit.
● When operating the unit with the door and windows opened, (the room humidity is always above
80%) and with the air defl ector facing down or moving automatically for a long period of time,
water will condense on the air defl ector and drips down occasionally. This will wet your furniture.
Therefore, do not operate under such condition for a long time.
● If the amount of heat in the room is above the cooling capability of the unit (for example: more
people entering the room, using heating equipments and etc.), the preset room temperature
cannot be achieved.
● This appliance can be used by children aged from 8 years and above and persons with reduced
physical, sensory or mental capabilities or lack of experience and knowledge if they have been
given supervision or instruction concerning use of the appliance in a safe way and understand
the hazards involved.
Children shall not play with the appliance. Cleaning and user maintenance shall not be made
by children without supervision.
● Do not climb on the outdoor unit or put objects on it.
● Please switch off the unit and turn off the circuit breaker during cleaning,
the high-speed fan inside the unit may cause danger.
● Turn off the circuit breaker if the unit is not to be operated for a long period.

!
● The product shall be operated under the manufacturer specifi cation and
not for any other intended use.
● Do not put water container (like vase) on the indoor unit to avoid water
dripping into the unit. Dripping water will damage the insulator inside the
unit and causes short-circuit.
● Do not use any aerosol or hair sprays near the indoor unit. This chemical
can adhere on heat exchanger fi n and blocked the evaporation water
fl ow to drain pan. The water will drop on tangential fan and cause water
splashing out from indoor unit.

AIR SLEEP MODE
The sensor detects changes to the infrared generated by human bodies. Therefore, the accuracy of sensor may be
affected in the following cases:
■ The activity level is very low (reading, watching TV, etc.) or human bodies are blocked by a screen, cabinet or
glass board.
■ The indoor temperature is very high and exceeds or approaches the human body temperature (when the refrigeration
just begins).
■ The person wears thick clothes and turns his/her back to the air conditioner.
■ Curtains or plant leaves swing due to pet movement or airfl ow.
With the air sleep sensor, the air conditioner can monitor the activity/movement level in a room and adjust the temperature
and humidity automatically, thus achieving the purpose of comfortable sleep environment and enegry saving.

Adjustment of the conditioned air to the left and right.
Hold the second vertical air defl ector of each set of vertical
air defl ectors from right as shown in the fi gure and adjust the
conditioned air to the left and right.
● If the “ (AUTO SWING)” button is pressed once,
the horizontal air defl
ector swings up and down. If the
button is pressed again, the defl ector stops in its current
position. Several seconds (about 6 seconds) may be
required before the defl
ector starts to move.
● Use the horizontal air defl ector within the adjusting range
shown on the right.
● When the operation is stopped, the horizontal air defl ector
moves and stops at the position where the air outlet
closes.
!
CAUTION
● In “Cooling” operation, do not keep the horizontal air
defl ector swinging for a long time. Some dew may form
on the horizontal air defl ector and dew may drop.
Adjustment of the conditioned air in the upward and downward
directions.
The horizontal air defl ector is automatically set to the proper
angle suitable for each operation. The defl ector can be swung
up and down continuously and also set to the desired angle
using the “
(AUTO SWING)” button.
Do not insert a fi nger, a rod or other objects into the air outlet or inlet as the fan is rotating at a high speed,
it will cause injury. Before any cleaning or adjusting the defl ectors, be sure to switch OFF the operation.

MAINTENANCE
Cleaning and maintenance must be carried out when fi lter lamp lights. Before cleaning, stop
operation and switch off the power supply.
1. PRE-FILTER
Clean the Pre-fi lter, as it removes dust inside the room. In case the Pre-fi lter is full of dust, the air
fl ow will decrease and the cooling capacity will be reduced. Further, noise may occur. Be sure to
clean the Pre-fi lter following the procedure below.
!
CAUTION
1
Open the front panel and remove the Pre-fi lter
● Gently lift and remove the air purifying fi lters
from the air purifying fi lter frame.
2
Vacuum dust from the Pre-fi lter and air purifying
fi lter using vacuum cleaner. If there is too much
dust, rinse under running tap water and gently
brush it with soft bristle brush. Allow fi lters to
dry in shade.
3
● Re-insert the air purifying fi lter to the fi lter
frame. Set the Pre-fi lter with “FRONT” mark
facing front, and slot them into the original
state.
● After attaching the Pre-fi lters, push the front
panel at three arrow portions as shown in
fi gure and close it.
!
CAUTION
● Do not wash with hot water at more than 40°C. The pre-fi lters may shrink.
● When washing it, shake off moisture completely and dry it in the shade; do not expose it directly
to the sun. The pre-fi lters may shrink.
● Do not use detergent on the air purifying fi lter as some detergent may deteriorate the air purifying
fi lter electrostatic performance.
NOTE:
● Air purifying fi lter should be cleaned every month or sooner if noticeable loading occurs. When
used overtime, it may loose its deodorizing function. For maximum performance, it is recommended
to replace it every 1 year depending on application requirements.
